Euphorbia amygdaloides ‘Robbiae’
For gardeners on the lookout for plants with multi-season interest, this perennial euphorbia merits examination. In spring and summer, rosettes of leaves are a shiny deep green, a good backdrop for sprays of chartreuse flowers in late spring/early summer. In fall, it dazzles with rich purple shades, and it still provides structure in the winter garden. Hardy to zone 6, this 18-24” euphorbia wants sun to part shade. Give it average garden moisture and soil, not too acid. It will tolerate drought. A big plus—it’s deer resistant like most euphorbia. Do be careful of the stem sap, which can irritate skin. Wear gloves when handling it.
